IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 174,851, dated March 14, 1876 application iiledf 7 December 17, 1815.

To all whom it may concern:

Be it known that we, ALoNzoW. PORTER Q bureter, and Fig. 2 is a front view thereof,

This invention has relation to improve ments in apparatus'for' carbureting air or gas by Volatilizing a hydrocarbon fluid.

' The object of the invention is to provide means whereby the hydrocarbons-will be maintained at the temperature of about 609 Fahrenheit, being that. best suited to the purpose, thereby counteractingand neutralizing the tendency of the evaporation of the hydrocarbon fluid to produce a Verylow temperature in the car.-

. bureting chambers inimical to volatilization;

also, to prevent the hydrocarbon spirits from reaching so high a temperature as by its too rapid evaporization to. supercarburct the air or gas, cool in the pipes, and J condense, as will be hereinafter more fully .set forth; als

to.. provide means, substantiallvas hereinafter described, whereby the hydrocarbon fluid will be automatically fed into the car-- bureting -chambers, .01 shut off therefrom, whereby the quantity of the fluid in the said chambers willat all times be kept on amean level and vinquantity best suited .to the proper enriching of the air o fgas'; andalso, in combinlng with a gasor air. carbureter a water- J jacket surrounding the ame, and a steam-coil for. heating the water, a thermostat, which is operated automatically to admit steam into the coil or to shut it off therefrom, by the lowering or raising of the temperature of the water in the jacket, as will be hereinafter more fully set forth.

In the. annexed drawings,the'letter A designatesa tank of suitable dimensions, in the lowor part of which is arranged a steam-coil, B', coinmunicating,,by means of a pipe, a, with a suitable steam-generator. Within this tank is supported, by meansof suitable legs, a carbureting-vessel, O, of similar form, which is divided,by means of a metallic partition, b, into two parts, D D, the. upper one being designed as a tank for storing the-hydrocarbon fluid, which is fed into .it through apipe, 'E. Thelower compartment D is provided with a number of spaced partitions, c,-by means of which it is divided into an upper. and a lower carbureting-chambel, designated respectively by the letters F F, so spaced as to form a .waterspace, d, between the oil-tank D and chamber F, and between the latter, and cham ber F,whioh chambers-communicate with the water-space d, between the vessel 0 and tank A, by means of perforations c. Cha n-p bers F F communicate witheach other by means of an overflowpipe,e the 'objcctvof which will hereinafter appear. y

e 0 represents vertical-spaced partitions-an,- ranged across chambers F F, and attachedto its walls alternately at one side and the other, whereby a serpentine passage in each chamber is formed from the airor gas: inlet in the lower chamber .to the pipe 6 and across the upper chamber to anv outlet-pipe, 6

through which the enriched gaswill be fedto the, burners or let into the ::upper part of v I p G represents a'second closed: vessehar ranged I beside vessel: 0 in tank A, which ves-' sel communicates with, carbureting-chambers F F by means of pipes f f, which openinto the 'said vessel, the one above and the other; belowa horizontal partition, .9, which forms in the said vesseltwo chambers, g 9

H represents afloat of suitable material, arranged in chamber 9 the shaft H of which passes through a sleeve, h, on partitiong into chamber 9 andis pivoted to the power endof a lever, H operating the slide of a valvearranged in a valve-box, H This box" communicates, by means of a, pipe, H with the lower' part of tank D, which pipe is provided with a pet-cock, by means of which LlllS communication is interrupted when requisite.

The operation of automaticallyfeeding the iydrocarbon to the carbureting-chambers .is

is follows The said chambers beingempt-y,

t-he float will hold the valve in valve-box H )pen, and if the hydrocarbon bepour ed into :ank D through feed-pipe E, it will pour ahrough pipe H into the said box, and

;l1rough an outletpipe, fl, into chamber g "r0m which it will flow into carbureting-chaln- )er F, and, having attained a certain level ;hrongh overflow-pipes into ,thelower cha n-1 )er F, from this chamber it will escape,"

;hrough pipe f, into the lower chamber 9 of ressel G,'and, having accumulated in suflicient iuantity, w r i floa .Ethmt y dosin :he valve in box H, andcntting ofl the sup- )ly of hydrocarbon from the said box until be level of the latterin chamber 9 has been inflicieutly lowered, when the float will fall,

As the water rises in temperature 'it will cause the pirits in vessel or disks k k toexpand, thussisin g rod j, and actuating slide l-to cut olf-the )mmunicationbetween the coil and genera- )r. The steam being thus cut off the temerature of the water in spaces (1 d will speedily lower, when the vessel is It will collapse-,this movement being expeditedby the recoil-of springeS-i-and reopen the valve and readmit the steam to the coil.
